Answer:
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
Step-by-step explanation:
A) Mean life expectancy of women
from the attached table
mean life expectancy of women = ∑fx / ∑f
∑fx = 1523
∑f = 20
mean = 1523 / 20 = 76.15
The line graph shows a negatively skewed distribution
B) Mean life expectancy of Men
from the attached table
mean life expectancy of Men = ∑fx / ∑f
∑fx = 1432
∑f = 20
mean = 1432 / 20 = 71.6
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
5/8 - 3/10
Find the common denominator:
Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)
Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)
5/8 = 5*5 / 8*5 = 25/40
3/10 = 3*4 / 10 *4 = 12/40
Now you have 25/40 - 12/40
25 -12 = 13
Answer = 13/40
The answer is A.
i’m doing big ideas too smh. you will keep change flip. and change them to an improper fraction.
so improper fraction times (flipped) other fraction
